MACHINE FOR CRUSHING ND SCREENING QUARTZ.

SPECIFICATION forming part of Letters Patent No.358,292, dated February 22, 1857.

(No model.)

.To all whom it may concern:

Be it known that I, JOHN E PARAMORE, of Vausau, in the county of Marathon, and in the State of Wisconsin, have invented certain new and useful Improvements in Machines for Crushing and Screening Quartz, Src.; and I do hereby declare that the following is a full, clear, and exact description thereof.

Myinvention relates to amachine for crushing and screening quartz and other mineralcontaining substances; and it consists in certain peculiarities of construction and combination of parts, as will be hereinafter described and claimed.

Figure 1 of the drawings represents a side elevation of my crushing and screening mechanism andasectional elevation of a mining pan or settler used in connection therewith; Fig. 2, an end elevation of the crushing and screening mechanism, and Fig. 3 a perspective view of one of the sieves.

Referring by let-ter to the drawings, A A represent vertical standards that are suitably braced apart to form the main frame of my machine, said standards being provided with bearings for the shafts B B of a series of horizontal crushing-rolls,C,vertically arranged in pairs. The vertical standards A A are also provided with brackets b, having journals c for gear-wheels D, the latter meshing with gear` wheels E, j onrnaled to the shafts B of the crushing-rolls O. These gear-wheels E in turn mesh with gear-wheels E', journaled to the shafts B of the other crushing-rolls,and by this arrangement of gearing the several crushing-rolls are made to turn toward each other.

The crushing-rolls C may be either smooth or corrugated upon their surfaces, or the upper pair of rollers may be corrugated and the lower pairs smooth, this latter construct-ion being shown by Fig. l. f

The bearings in the standards A A for the roller-shafts B B', either of the upper pair of rolls only or of all of said rolls, are slotted, as shown at a, and said shafts are provided with boxes a', against which impinge springs a2, also placed in the standards7 slots. This construction serves to retain the rollers G in their normal position, but at the same time allows a yielding motion should any substance of more than ordinary size or hardness be fed thereto from the hopper.

'Ihe shaft B of one of the lowest crushingrolls is extended to form a main shaft, F, an additional bearing, d, for the same being provided at the top of a vertical post, G. This main shaft F has keyed thereto a beveled gearwheel, I-I, designed to mesh with a similar Wheel, I, keyed to a vertical shaft, K, having its bearings in brackets e, secured to the vertical post G, a bracket, f, projecting from one of the frame-standards, and a socket, g, on a basepiece, M.

The upper end of the vertical shaftK is provided with an eccentric, lz, having a rod-connection,i, with a hopper,N, loosely hung by links k to the main frame, so as to have a vibratory motion when said eccentric is operated,whereby the quartz or other substancein said hopper will be prevented from clogging on its passage to the rolls. Hung by links m to the main frame, a suitable distance below the crushing-rolls, are a series of horizontal sieves, O, united at their ends by vertical strips n, one of said strips being connected to the rod o of an eccentric, p, secured to the vertical shaft K.

In practice it may be found desirable to graduate the meshes of the sieves, giving the upper one the coarser, thelower one the ner, and the middle one an intermediate mesh. I have not speciallyillustrated this feature, nor do I make any claim to the same, it being a matter entirely of preference.

By the above-described connection a vibratory motion is imparted tothe sieves when the vertical shaft is revolved. Near its lower end the shaft K has keyed thereto a beveled gear- Wheel, I), that meshes with a similar Wheel,Q, on the adjacent vend of a horizontal shaft, R, that revolves in bearings r on'the base-piece M. r)This shaft Q, at its other end, carries another beveled gear-wheel, R', that meshes with a like wheel, S, on the vertical shaft T of a settlingpan,U, employedin connection with the crushing and screening mechanism, saidshaft'lhaving its bearings in a socket, s, on the base-piece lVl and a bracket,V, the latter project-ing from the main frame of my machine. Y

` The settling-pan U and its shaftT are preferably of a construction similar to that enr bodied in my application for patent filed December 2, 1885, Serial No. 184,429, and further description thereof is not deem-ed necessary in IOC this application, inasmuch as a different construction of said parts may be employed with mycrushing-machine. Suitablysuspendedin theinain frame belenY the sieves O is a trough, YV, that conducts the tailings from said sieves to the settling-pan.

In the operation of my invention motion is imparted to the various parts of the machine through the medium ofthe main shaft'F. The quartz or other snbstanceis fed from the vibrating hopper N tothe crushing-rolls C,aud from thence. to the vibratory sieves O, where the coarser metallic particles are separated and re tained, the residue passing on down to the trough XV, from whence it is conducted to the settling-pan U, to be acted upon by water, said pan being revolved at a high rate of speed to better accomplish a thorough washing of such residue or tailings from the crushing and screening mechanism. By this Washing ofthe residue or tailings, the heavier portions or metals that may have escaped through the sieves are freed from thesurrounding substanees,and being of greaterspecitic gravity tend to remain in the pan,while the lighter particles are carried oft' with the overflow of the Water.

Having thus fully described my invention, what I claim. as new, and desire to secure by Letters Patent, is-

1. A machine for separating metal from quartz or other substance, comprising a main frame, a series of horizontal crushing-rolls vertieally arranged in successive pairs, a vibratory hopper located above the rolls, a series of Vibratorysieves arranged below the lowest pair of rolls, and means, substantially as described, for simultaneously operating said rolls, hopper, and sieves, as set forth.

2. A machine for separating metal from quartz or other substance, comprising a main frame, a series of horizontal crushingrollsvcr tical] y arranged in successive pairs, a series ot' vibratory sieves beneath the lowest pair ot crushing-rolls, a revolving settling-pali operatively connected to the frame, a. trough arranged beneath the lowest sieve to lead to the pan, and means, substantially as described, for simultaneously operating said rolls, sieves,and pan,whereby the quartz or other substance is successively crushed, screened, and Washed by a single machine, as set forth.

In testimony that I claim the foregoing I have hereunto set myhanrhat lWausau, in the county of Marathon and State of iViseonsim in the presence of two Witnesses.
